The Resynthesizer Plugin Suite contains a practical tool for Gimp that allows you to remove the objects in your pictures after covering them with the adjacent elements. In the post I describe a Linux installation procedure of the version 2, by compiling the source from GitHub or by executing an executable and an example of its use.

Gimp1 is a fantastic raster graphics editor, open source and available in many languages and platform. Indeed it is expandable and extensible; it is designed to be augmented with plug-ins and extensions in order to improve its functionality. One of the most powerful is Resynthesizer Plugin Suite and its Heal selection filter: a useful feature designed for removing unwanted objects in images and can often be used to repair wider cracks, creases, and other large areas of damage.

Installation

The Resynthesizer Plugin Suite is open source and so there are two methods for installing it in your platform:

by compiling it from the source in the GitHub repository;

by packages that contains it and others plug-ins, scripts etc. for GIMP.

GitHub

Although the main files are very old (updated 4 years ago), the GitHub repository contains the Version 2.0 that

it is a complete rewrite and is multithreaded. Otherwise, functionally the same except when compiled threaded it is nondeterministic. See ChangeLog for more discussion. From: bootchk/resynthesizer - GitHub

Assuming that you don’t have any older versions installed in your system you have to:

Directly

There are several collections of extensions for GIMP that provide the ability to choose which Plug-ins, Scripts, Brushes, etc, that you want to install with a fast setup starting from an executable. Some of them contain the Resynthesizer plug-in, here they are:

An example

In the gallery below there is a typical example of the heal selection filter in action (Filters -> enhance -> Heal selection...) using a shot from the Side of Sant'Antonio Abate Church in Pisa with mural by Keith Haring4.

At the end the obtaining image is made only with hand tool and Heal selection filter. It is not perfect but requires some additional work to obtain an excellent outcome.
